- STEAM-INJECTOR.

SPECIFICATION forming part of Letters Patent N 0. 674,180, dated May 14,1901. Application filed April 24, 1900. SerialNo. 14,126. (ModeL) I Toall whom it may concern: 4

Be it known that I, FRANCIS STICKER, of

New York, in the county of New York and State of New York, have inventedcertain new and useful Improvements in Steam-Injectors and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention has reference to steam-injectors.

The primary object of the present improvements is to provide a singlecock or valve for controlling the steam and water inlets and the primaryand auxiliary overflows and also in some instances the boiler-outlet.

A further object is to provide for the ready removal of one set of tubesin a manner which will render unnecessary the handling of each tube.

1 These features may be introduced into a single or double jet machine,and in thelatter class the lifter may be located above the forcer, asshown and described in Letters Patent No. 600,456, issued to me March 8,1898.

There are various ways by which the present invention may be carried outembracing means for controlling the operation of a ma chine byregulating the supply of steam or water, or both.

The invention will be hereinafter fully set forth, and particularlypointed out in the claims.

In the accompanying drawings, Figure'l is a vertical longitudinalsectional view of an injector constructed in accordance with the presentimprovements, the lifter being shown above the forcer. Fig. 2 shows asimilar view with a slight modification. Fig. 3 is a centrallongitudinal sectional view of an injector in which the tubes of theforcer are shown as mounted in a controlling valve or cook. Fig, 4: is aview of a modification in which the lifter is located above the forcer.

Referring to the drawings, A designates the casing, having steam-inleta, water-inlet a, overflow a and boiler-outlet a B is a single cock orvalve conically outlined, held by any suitable means within acorrespondinglytapered opening extended longitudinally of the casing.This cock is formed with steam ports or chambers 1 and 2 for theforcerand lifter, respectively, steamtube 3 and combining and deliverytube 4 of the lifter being mounted in partitions of the cook, theopposed ends of said tubes opening into the water-chamber 5. Thischamber re ceives-its supply ofv water through side ways leading fromthe inlet a. The delivery-tube empties into the discharge-chamber 6,which in starting registers through a port 7 with the overflow 0, Thischamber 6 also discharges into a lower water-chamber 8 of the forcer,which latter has its steam-jet 9 and combining and delivery tube 10. Theforcer opens into discharge-chamber 12, which until the jet isestablished has. communication with overflow a through a port 13; butwhen the cock is turned the jet passes from chamber 12 through a port 14in the cock directly to the boiler-outlet. may be manipulated byanysuitable means, preferably a hand-lever.

It will be noticed that the cock B carries the tubes of the lifter andalso that it controls the steam and water inlets and the primary andauxiliary overflows. In the form indicated in Fig. 1 it also controlsthe boileroutlet, in that port 1 1 is not brought into play until theoverflow 13 is closed. In practice steam is'first admitted through inleta and the cock is turned sufficiently to allow the steam to enterchamber 2 thereof and then pass through the tubes of the lifter to theoverflow, and upon reaching the outside atmosphere a vacuum is createdwithin the casing, and especially Within the water-chamber 5, whereuponwater is lifted, and the steam in the combining-tube being condensed Thestem 15 of the cook the water will be taken up and upon being dischargedinto chamber 6 a portion will pass into the overflow and the remainderinto chamber 8 of the forcer. The cock being by this time turnedsufficiently to admit steam through chamber 1 to the tubes of theforcer,the water will be discharged by the latter into chamber 12. The jetbeing fully established,

.the operator further turns the cock, closing the overflows throughports 7 and 13 and opening up communication between the chamber 12 andthe outlet to the boiler. By turning the cock I am able to regulate theextent of the steam-supply and also the extent of the water taken up bythe lifter and the discharge of the latter into the water-chamber of theforcer. Not only do I obtain the advantage of controlling the inlet andoutlet passages, but by mounting one set of tubes in the cock access maybe readily had to them for the purpose of inspecting, cleansing, orsubstitution by merely withdrawing the cock from the casing.

I do not intend to limit myself to any particular form of embodiment ofthe special features of this case. It is obvious that substantially thesame results may be obtained in various ways without departing from thespirit or scope of my invention.

In Fig. 2 the relative direction of passage of the steam and waterthrough the tubes of the lifter O is reversed after the manner shown inLetters Patent No. 600,455, issued to me March 8, 1898. By turning thecock steam is admitted to steam-chambers 16 and 17 of the lifter andforcer, respectively. The water-chamber 18 is connected by side wayswith the Water-inlet l9, and the dischargechamber 20 of the lifterempties into the water-chamber 21 of the forcer D. This latter chamberwill in starting allow the discharge through port 22 to theoverflow-opening and also what is termed the primary discharge of theforcer through a port 22; but when the jet is established the cock isturned so as to cut oif both ports 22 22 and allow the jet to pass fromthe forcer into the extended end of the cock and thence to the boiler.In Fig. 3 I have shown the tubes of the forcer E located in the cock F,which latter controls the steam from inlet 23, water from thedischarge-chamber 24 of the lifter, and also the overflows, which latterare had through ports 25 and 26 for the lifter and forcer, respectively.Hence by turning the cock, with the tubes of the forcer mounted therein,I am enabled to control the steam and water supplies and both theprimary and auxiliary overflows after the manner hereinbefore described.I have indicated a check-valve at 26, which is normally held to its seatby the boiler-pressure.

The tubes of the lifter are shown in Fig. t as being located in cock G,having, like the forms shown in Fig. 1, two steam-chambers 27 and 28,the discharge-chamber 29 of the lifter opening into the water-chamber 30of the forcer. The discharge of the lifter and that of the forcer intooverflow 31 are controlled by turning the cock. When these overflows areclosed, the established jet will unseat check-valve 32, which is shownas having its seat on the inner end of the cock.

The advantages of my present improvements are apparent. It is obviousthat, as hereinbefore stated and as demonstrated by both thespecification and drawings, various modifications of the underlyingfeature may be readily adapted. In some instances one or more directways for the passage of the steam and water are provided, and inconsequence there is but small loss from friction, heat, and pressure.

I claim as my invention 1. In a steam-injector, a chambered valve orcook removably held within the injector, and a series of tubes mountedin said valve or cook and opening into some of the chambers thereof, asset forth.

2. In a steam-in j ector, a single valve or cock having a series ofchambers with dividingpartitions, and a series of tubes mounted in someof said partitions, and means for turning such valve or cook.

3. A steam-injector provided with a steaminlet, water-inlet, and primaryand auxiliary overflows, and a single valve for controlling said inletsand said overflows.

4:. A steam-injector provided with a steaminlet, a water-inlet, aWater-overflow, and a boiler-outlet, and a single valve or cock forcontrolling said inlets, overflow and boileroutlet.

5. The combination with the casing, of the sets of forcer and littertubes, and a single valve or cook in which one set of tubes is mounted,said valve or cock having ports and chambers therein for controlling theinlet of steam and water and the overflow of both the lifter and forcer,substantially as set forth.

6. The combination with the casing, of the forcer having its tubesmounted in said casing, a single valve or cook fitted in the latter andhaving ports and chambers, and the lifter having its tubes mounted insaid valve or cock, which latter by being axially turned will controlthe steam and water inlets and the overflows of the lifter and forcer.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.

FRANCIS STICKER.
